I liked Ike's PoR voice. I thought it matched him perfectly.
I don't see the problem with Pit's voice, he sounds how I would have expected him to sound.
Fox's was a little weird in the beginning, but I'm used to it by now. And I like Falco's.
I'm still a little sad Marth doesn't speak English; I don't care how bad he'd sound, it would kind of soothe the pain of having characters most of us have never played or some even heard of in Brawl (Lucas and Marth, yes I do hate the fact that Japanese characters in this game, even if I'm going to be trying to main Lucas

).
I like Ike's voice, as people have stated before, the others who think otherwise probably haven't played PoR, or hated his voice from that game, so I don't see what the big deal is.
EDIT: "You'll get no sympathy from me!"
I think quarter would sound better there.
